2. KEY VOCABULARY Evidence Something that is helpful in forming a conclusion and is supported by data. Extinct A species in which the last member dies without any surviving offspring. Extinction is the process of becoming extinct. Fossil A remnant or impression left by an organism that lived in the past. Geologic Time Scale is a system of chronological measurement that relates to time, and is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. Species A group of organisms with similar characteristics and evolutionary history that can successfully reproduce. Taxonomy the branch of science concerned with classification of organisms.

3. Copy the following questions in your science notebook What are the basic needs or requirements of all living animals? The ability to eat or ingested food, ability to breathe (exchange gases) and the ability to grow List the 7 life processes. Movement, Sensitivity, Nutrition, Respiration, Growth, Excretion, Reproduction What is sensitivity? Sensitivity is the ability of a living organism to respond to external conditions Learn more about Taxonomy

4. What are the 2 forms of reproduction for all living organisms? Sexual and Asexual. Sexual requires 2 parents, Asexual requires only one Where do most scientist believe all life began? Most scientist believe all life began in the oceans Explain how a bottle nose dolphin can withstand the tremendous pressures of deep water that human cannot. A bottle nose dolphin can withstand the tremendous pressures of deep water due to the fact they have a flexible rig cage that will contract and expands as they move in and out of deep water. This is an adaptation to their environment that humans do not process According to the video, how do scientist define life? The video states seven life processes. According to the video, to classify an organism as living, it must be able to carry out these 7 complex processes which cause it to survive.

Watch the first video clip from the list: “Characteristics of Living Things” As you view the video clip, answer the questions from the previous slide. You can always pause the video or go back and re-watch it as need. After you have completely answered the questions, you may work on an assignment from another class, or you may read. Do not continue on to the next slide. The rest of this lesson will be complete in the classroom.

8. 1. Review your notes on the eight different types of fossils. Do you think any of them are from similar species? Explain, using evidence from this activity to support your answer. Although none of the eight fossils are identical to any other one, there are some similarities. Such as basic body shape or features such as shells. These remains could indicate some similar and perhaps related organisms.

9. If you were an actual paleontologist or geologist collecting fossils, you would be able to observe its surroundings. For example, the rock layer in which the fossil is found can provide information about the fossil’s age and whether it was found in an aquatic or land environment. Other fossils nearby might tell something about the organism’s behavior. For example, it might establish if the organism tended to live in groups, or it might provide evidence of predator and prey relationships.

10. The Ammonite might have been a snail. It had a hard shell covering possibly a soft body, and the pattern of the shell looks like a snail’s. It curls around itself and had tiny ridges on it. The Ammonite (if it is some type of snail) may have lived on land in a moist environment, like a garden. There would have to be enough water so that the soft part of the body does not dry out and it has food to eat.

11. In examining the details of some fossils, the easiest information to determine could come from the bones can provide very good evidence for overall size, shape, and information on how they moved. The teeth can indicate a lot about feeding habits. The physical traits such as skin color and texture would be details much harder to determine from fossils. In addition, behavioral traits, such as social interactions and mating patterns, and physiological traits, such as warm- vs. cold-bloodedness would alos be very difficult to determine.
